+    \qmlclass ListModel QDeclarativeListModel
+    \brief The ListModel element defines a free-form list data source.
+
+    The ListModel is a simple hierarchy of elements containing data roles. The contents can
+    be defined dynamically, or explicitly in QML:
+
+    For example:
+
+    \code
+    ListModel {
+        id: fruitModel
+        ListElement {
+            name: "Apple"
+            cost: 2.45
+        }
+        ListElement {
+            name: "Orange"
+            cost: 3.25
+        }
+        ListElement {
+            name: "Banana"
+            cost: 1.95
+        }
+    }
+    \endcode
+
+    Roles (properties) must begin with a lower-case letter.  The above example defines a
+    ListModel containing three elements, with the roles "name" and "cost".
+
+    The defined model can be used in views such as ListView:
+    \code
+    Component {
+        id: fruitDelegate
+        Item {
+            width: 200; height: 50
+            Text { text: name }
+            Text { text: '$'+cost; anchors.right: parent.right }
+        }
+    }
+
+    ListView {
+        model: fruitModel
+        delegate: fruitDelegate
+        anchors.fill: parent
+    }
+    \endcode
+
+    It is possible for roles to contain list data.  In the example below we create a list of fruit attributes:
+
+    \code
+    ListModel {
+        id: fruitModel
+        ListElement {
+            name: "Apple"
+            cost: 2.45
+            attributes: [
+                ListElement { description: "Core" },
+                ListElement { description: "Deciduous" }
+            ]
+        }
+        ListElement {
+            name: "Orange"
+            cost: 3.25
+            attributes: [
+                ListElement { description: "Citrus" }
+            ]
+        }
+        ListElement {
+            name: "Banana"
+            cost: 1.95
+            attributes: [
+                ListElement { description: "Tropical" },
+                ListElement { description: "Seedless" }
+            ]
+        }
+    }
+    \endcode
+
+    The delegate below will list all the fruit attributes:
+    \code
+    Component {
+        id: fruitDelegate
+        Item {
+            width: 200; height: 50
+            Text { id: name; text: name }
+            Text { text: '$'+cost; anchors.right: parent.right }
+            Row {
+                anchors.top: name.bottom
+                spacing: 5
+                Text { text: "Attributes:" }
+                Repeater {
+                    dataSource: attributes
+                    Component { Text { text: description } }
+                }
+            }
+        }
+    }
+    \endcode
+
+    The content of a ListModel may be created and modified using the clear(),
+    append(), and set() methods.  For example:
+
+    \code
+    Component {
+        id: fruitDelegate
+        Item {
+            width: 200; height: 50
+            Text { text: name }
+            Text { text: '$'+cost; anchors.right: parent.right }
+
+            // Double the price when clicked.
+            MouseArea {
+                anchors.fill: parent
+                onClicked: fruitModel.set(index, "cost", cost*2)
+            }
+        }
+    }
+    \endcode
+
+    When creating content dynamically, note that the set of available properties cannot be changed
+    except by first clearing the model - whatever properties are first added are then the
+    only permitted properties in the model.
